Originally a hip-hop/rap group, but now can be used in slang to refer to any group of scary-ass gangsta-looking black people.

Usage Warning:
Use when not in the presence of black people.
Boy: Oh shit, a three six mafia just walked in the club.

Boy's friend: Let's bounce. I wanna hit the bar next-door anyway, there are no hot girls.
